Abstract:
This article reviews the recent advances in microfluidic-chip integrated optical biosensors for simultaneous detection of multiple analytes. In particular, the principles and recent progress in different kinds of multiplex optical biosensors and their biological application were reviewed comprehensively. Sensors based on multiplexed detection have absolute advantages in analysis throughput than single assay. The microfluidic chip, a type of micro-total analysis system (µTAS), provides an ideal platform for integration of high-throughput biosensors. Compared with electronic biosensors, benefitted from the technical development in Micro-Electro-Mechanical System, there have been greater advances in the fabrication of optical sensors and microfluidic chip, and then promoting microfluidic-chip integrated optical biosensors for simultaneous detection of multiple analytes.

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...
